Using addons

[Challenger]

well, im making a campaign, and i am planning on using several addons. i allready have permission for about 3 of them, but i was wandering, do i really need to ask for addons (several people have told me no)

Challenger ;D

I'm pretty sure all AddOn makers have made their AddOns to be used, so there's really no point in asking is it ok to use them..

However, in case of modifying the AddOn or re-distributing it in a different form than the original package etc. asking permission is a good practise...
If not even a requirement because there will be a lot of bad blood if something is done to someones AddOn without asking the author(s) first..

So for using, no need to ask permission...
