Oh no! That is terrible. Hopefully you have a phone and can do some things from there. I post daily on Actifit from my phone, and do most upvoting on my phone. It's nearly impossible to do anything complex like contests without a good computer, however.

Do you have access to a library that has computers? One thing you could think about doing is creating a template in Google docs with all your formatting. Then you can click in the doc, click Select All and paste into a new post. Then you just have to edit. This might make it possible to continue your contests until have a functioning laptop again.
