[Edit] Please note that point #3 has been changed. Trion originally posted a previous incarnation than the one they eventually settled on as their final version. The old, incorrect, one read: Add-Ons, including the Add-On website or distribution site, may not include advertisements of any kind, including in-game requests for donations, unless expressly permitted by Trion.

does that mean authors of Rift AddOns cannot recieve paypal donations etc?

That's not the way I read it. It says they (the authors) can't charge, they (the authors) can't require compensation. It doesn't say people aren't allowed to voluntarily send them (the authors) a couple bucks if they (the users) feel like it.

ahh thats cool then.

As always, though, please note that IANAL and IANATE. ;)
