There are two options:
1. Make me a super moderator.
2. Create a subsite offtop.heroesworld.ru in the form of a forum, where all non-themed sections (which are not directly or indirectly related to Heroes and M&M and which are not work-related) and the mini-chat will be moved. All off-topic posts on the forum will be deleted, and this will be strictly monitored, unless the off-topic post is tagged with [off]. Introduce a corresponding item in the rules and, instead of the mini-chat at the top of the page, add a link (with a comment) to offtop.heroesworld.ru.
