Starting up a bit of a conversational topic, but let's say you've got some time and you're looking for an RP to join. What is it that you look for in an interest check and what is it that guides your decision to apply for a roleplay? Expanding out a little more but after a roleplay transitions from Interest Check to OOC there are always a small chance that people may pull back and decide not to enter, so what would be some of the reasons that may change an applicant's enthusiasm? 

Discuss and explain. Include your experiences as a GM and/or as a Player.
