Usually I post a link in a related spot. For example, one of my Favorit baseball players is Blake DeWitt and I wanted to make a spot for him. After I did I gepostet Links to it in the baseball spot and the spot for the team he plays on.
Just don't spam - that's the easiest way to get people to NOT Mitmachen your spot (aside from making a really pointless spot that already has similar "sibling spots" - example, someone recently made a spot for House's CURRENT team when there is already a spot titled "House's Team")
Well, there shouldn't be any annoyingness going on and about, Du want people to Mitmachen your club, right? Then do it! :) No ones stopping you! No ones hurting you! It's truly is simple. But don't forget, when Du want someone to Mitmachen your club, act like Du mean. If so, write something on their page. Something that may inspire them to Mitmachen your club! >Hope this helped. :/ hang in there. :)
