Community Server question

I'm launching a server soon and if possible I'd like to have it in the Community tab in the server list.

The server is completely Vanilla, no modifications to the gameplay.
I read the guideline about adding Modded="" to your config but I have a couple questions to what it's permitted or not.

- I use a couple SQL Database plugins, this is crucial for my server, are they allowed?
- I have a custom plugin that is basically sends texts for commands  [ChatCommand(), player.ChatMessage], is it allowed?
- Clans plugin, allowed?

If anyone knows better about this rules, I'd appreciate your input!
Thanks in advance!
