Welcome to WetCanvas! and the Oil Forum in particular.
Some of you are new to oil painting and as you enter our community I am sure you have a lot of questions. Needless to say, many of your questions have been asked many times here on WC and some interesting and educational discussions have already taken place.
This isn't necessarily a replacement of your question though, so if what you are wondering isn't answered here (or by doing a search) please do start a thread with your question and get that good one-on-one that WC is so well known for!
Also, don't forget you can do your own search

here is an article that can help you get the most out of searching here on Wetcanvas:

This is an important thing to know if you intend to glaze or paint in layers!
"Noob Question - fat over lean?"
Glazing is often seen as some mysterious technique of the old masters, but it is really nothing more than painting in thin layers (often using transparent pigments though semi-transparent and opaque pigments may also be used when applied in a physically thin manner--some people will use the term "scumbling" when using opaque paint) which enable some of the previous layers to show through. Below are a few how-tos, though these are not the only ways that glazing may be accomplished. (You might also want to have a look concerning various mediums and the "fat over lean 'rule'", links which can be found above.)

Water Miscible Oils
*When doing a search for these, keep in mind that many refer to these as "water soluble"--and many misspell it as "soluable".
Many people love using these as an alternative to regular oils; they can be lightly thinned with water instead of solvent and can be cleaned up with soap and water (though soap and water does a fine job with regular oil paints, as well!).

Oil paints can be easily cleaned up with soap and water, though it seems that there are as many ways to clean up as there are oil painters!
How Do You Clean Up? -a poll
Varnishing serves two main purposes. First, varnish serves as a layer of protection between your painting and the environment--it is meant to be a removable layer. It also serves to even out the sheen of your painting if you have the glossy/dull patches which are quite common to oil paints. If you choose to varnish, you should wait six to twelve months after the surface is touch-dry (you may use "retouch varnish" to even out the surface before then if you wish). Varnishing is optional and in the case of needing to show or sell the work before the six month mark, it is a common practice to let the customer know they may return the piece at a later date to be varnished if they wish (with the added bonus of being able to interact with the customer again!).
Painting Supports (Surfaces)
*The most common surface for the beginning oil painter is stretched cotton canvas or canvas mounted on some type of board. (Often these cheaper boards are mounted on cardboard, this is fine for practice and learning but they do have a tendency to warp, especially at larger sizes, and these cardboard boards are often not seen as archival.)
*Commercially prepared canvas usually has 2-3 coats of acrylic primer (also known as acrylic "gesso" though real "gesso" that is traditionally used in oil painting is quite different). It is often fine to paint directly onto commercially prepared canvas, though the primer coating can be thin especially in cheaper brands and many people like to add a few more coats of acrylic gesso to ensure that the oil will not seep through the primer (thus rotting the canvas eventually) or merely to further obliterate the weave of the canvas, creating a slightly smoother texture to work on. I will reiterate, though, especially for beginner oil painters, there is usually no problem painting on the commercial canvases as-is.
*Another common surface for oil painters is board, hardboard or mdf being the most common (and least expensive, definitely cheaper than canvas). You can usually purchase hardboard at your local Home Depot or Lowe's-type place and it is usually quite inexpensive (cheaper than decent paper even). The shop will usually cut the board to your specifications and you can then prime it with several coats of acrylic gesso.

Visiting some of the other forums, such as the color theory forum, can be advantageous for the new painter too.
