Splitcoaststampers - Challenges question

I can't say it often enough or in enough places, so I'll say it again here hoping there are a lot of ladies reading this: Thank you for all the inspiration and resources. Many of the cards I make start with inspiration I find either here or in catalogs, etc. There is some amazing talent here and I appreciate a place like this site so much where everyone can come here to share and learn.

That said, is there a time limit to upload entries for challenges (ie, sketch or color challenges)? I realize that the Virtual stamp night challenges are time sensitive, but what about the others? Sorry, but didn't know where else to post this. Moderator, please feel free to move this to the appropriate section.

Thank you!
