Just a note, what is the deal with needing a feedback of 50 to start your own eBay Group? Under 50 not worthy, over 50 worthy. It's stupid. Thats' all about that for now.
I think it's because they want to make sure you're going to be a member of ebay for a while. People frequently join groups and then the leaders disappear. The leaders are the only ones who can make modifications to certain aspects of the group so someone with a feedback of 50 or more is more likely to stick around and stick to the committment they have made to it's members. It drove me crazy having to wait until I had 50 feedback points to start my group, so I understand.
