I've read the forum rules, but am still unclear on the following: Are we allowed to include links in our signatures to products we sell? I've noticed several members whose signatures contain links to their commercial websites, where they sell Mac-specific products. I'd like to do something similar *include a small notice in my signature inviting people to check out my company's books in the iBookstore but I'm not sure if this is permissible. Any feedback or advice that the community can offer me on this issue would be greatly appreciated! Thanks.
