Considering that there were recent issues with the size constraints, it is a practical move. I say go ahead, 2 years is very reasonable.
The written word doesn't eat up so much bandwidth...it is the bells and whistles that people attatch to their sig, or avatar. I can't believe that 3-4 mb's of written word would be that big of an issue. And it is a bit strange that the site crashed during a time there was very little going on, as opposed to during the season when we had 30 people in the chat room and 250 posts a day. In fact , when you compare this to other forums, there is very little going on concerning membership activity. The homepage appears to be taking up quite a bit of bandwidth as well. I stand by my comments that the historical record is very important, especially 2005-2007...i just hate seeing words being flushed. I am a member of many different forums, and i have never seen it become an issue.
