When posting resources, post .zip and/or .rar files preferably so people can download and unzip them.

Also be sure to specify which program the resource is intended for if it's a program specific file (IE: .flp files for FL Studio)

Be sure to give an idea of the size of the file if it's above 100kb

Update January 13, 2007: You can now post in FL Studio formats, no compression is required anymore, unless you wish to post multiple files.
Also, if you are posting more than 2 files, please compress them into a single file and post that.
