I have requested to join two sites in the past few weeks. However, neither of the site managers for these sites has replied. Even if they replied to say "no, you can't join", that would be something!
I cannot repeat the request to them (in case they didn't get my first request), because the system says I can't request again while there is still a request being evaluated by the site manager.
So what do I do? Just forget about the whole thing and look at other SmartMatches? One of the sites I requested to join had over 200 matches with me.
