Hi this is Kat, I am the customer service manager, admin, and moderator for this new community! I look forward to meeting all of you and sharing some great horsey stories!
If your sig is cut off it is because it is too wide. Sigs are set up to be a max of 400 pixels wide. Some that are cut off are around 600 pixels wide. All you need to do is go into photobucket, adobe photoshop, or another photo editing program and shrink it down to the correct size.
