Hi Annie,
Because the boards have been so busy, MB made some changes to the forums. The most obvious change is that the smileys don't automatically display over the messages anymore, and the YaBB code boxes too. All this is explained in the 2nd paragraph of MB's topic called "Bandwidth Saving Measures" that's stuck to the top of "Current Talk".
To summarize it for you, the smileys can be made to display again (MB gives the instructions) but instead of that we encourage you to access them when you need them by clicking on Help, then Posting, then Emoticons. Hopefully you'll come to memorize them and won't need to keep going to the Help section for the smileys you use often.
We're sorry to have to make these changes, but better this than risk that our server temporarily shut us down again or that we take other measures that would hit our visitors much harder.
