The reason I undid the edit on the Wyvern page was because it was absolutely broken. It was a mess of code that didn't work. I think you are overreacting to undo all of your other edits which as far as I can tell are 100% fine. It is also my fault for not remembering to add my rasoning to the undo.
I also deleted the Black Tentacles page because we are not a substitute for the DMG, PHB and MM in any edition. These books in both 5th and 2nd edition are still sold and as such any content from them we cannot just reprint. This goes for monster stats too.
We need policy pages to explain this I know but we've just been really busy. As such I hope you will come back to editing the wiki now I have explained why I undid your edit and deleted a page.
First I'll introduce myself - I'm the founder/admin of the wiki and so far I've only known you from the massive amounts of emails I've gotten through the past several days - notifications of your greatly appreciated edits and pages. I have to say, I love what you've been doing and anyone who invigorates the wiki with content is welcome here.
The mod team has been keeping track of your edits and so far they've been great, appreciated additions. However, I spoke to Zonalar this morning and there appears to have been some kind of misunderstanding? As I understand it edits of yours were deleted? If you don't mind, I'd like to get in touch with you (add you on skype or the like) and talk about it to hopefully resolve what's happened here because I'd hate to think that you'd been alienated by page moderation or something, and I am sorry if that happened - all of the wiki contributors are greatly appreciated and it's been great to open my emails in the morning to see all the stuff you've added. I look forward to hearing from you, if you're open to that.
