1: Oh my check the Blocksworld Wiki on the new "My Wikia" App!!! It looks so clean and prefect! BUT it won't load any CSS fonts I've put, so make sure to select the prefab "Serif" font to make it looking beautiful!
2: I don't know if it's you that modify your Wiki's Profile page (because it's not showing in the Recent changes...) but it automaticaly redirect to your Blocksworld profile. If it was you, I don't think that mixing these two accounts is a great idea... Also, please check your links, they are invalid and the source code isn't well applied. A complete url (e.g http://www.blocksworld.wikia.com) isn't like an internal page (e.g. User:PotterShaman). Please check Wikia basic tutorial to know how to writte it well.
What font would you like? My preference is Sans-Serif category, and that one was pretty the most beautiful and clearly font I founded. If you have any suggestions, please tell me! It's easy to change. I will also soon change the SourceCode font to Ubuntu, which is computer-space looking. It's very original but the difference from other fonts isn't too big.
