I know there are plugins that hide content until posts, but how could i do it so this option would only be enabled only in first post.

http://mods.mybb.com/view/hideuntilpost - Found this, but this can be used everywhere and when watching pritable version it shows hidden content
http://mods.mybb.com/view/hide-content-until-reply - This doesnt do the job either

Also how could i add restrictions to default reputation system so only users that have 100 posts could give rep or something like that, or is there another reputation plugin that allows this?

You can add some vars to core files.

But about the first mod, you have to add some hooks only thats all.

abous the second mod, you have to confugure it fine, then works, most peopple tolds the same, but they do not install or configure it fine, i teste since 1.6.3 version has released, and now i have the 1.6.11 version and works fine this mod, i put a forum with this released mod, and i am working on new version, but officially the mod was on 1.9 version, here are 1.8 the last i release on forums with Relased plugins.

If you wish we can test this mod in your forum and show how it works, and how can configure ir fine to do his job fine.

Cheers.

Or indeed you may able to do by yourself mading changes to your core files xD.
