Am I looking for wordpress?

Hello!

I’ve been using wordpress for a while now, but i don’t know if it’s a appropriate “template system” for my upcoming project.

The project: I’m going to make a community page where a group of 50-100 can arrange and view already planned arrangements.

1. The users should be able to fill out some online formulas where they specify what they arrange and when they arrange it.

2. When the formula is filled out properly the calendar on the page should show the changes.

Thanks in advance
