Gamer role, Clan Wars and search box

Hello again. I need a little help with Gamer role in Blackfyre. I found in functions.php line that can be changed to give another role as default, but Gamer doesn’t have acces to wp-admin and this is what I want to achieve. So can I safely set Gamer as default and don’t worry about it in the future, or this role has some permissions which should i know about?

Next thing – is it possible to turn Clan Wars into some kind of “clubs” for users? Without matches, games, just custom page and users list. I don’t know if this is question to you or creators of this plugin.

Last thing – how can I remove search box from blog sidebar?
