Hi John!

you could make a website with all your unofficial errata-work and ask for a voluntary donation through a Paypal-account. Though I do not know if this would be legal.

When 3.5 errata is concerned, I have only found this old thread in the Wizards-archives: DO NOT PRUNE: The 3.5 (potential) Errata thread [Archive] - Wizards Community

You could also open a new 3.5 errata subforum on the Wizards-community website for your future projects.

cheers!

Hi!

Thanx for doing the correction-work for the 3.5. MHB. You have been of great help to me.
How much of the share do you get of the sellings of "Cooper's Guide to Corrected Creatures"?
Do you offer an errata of the 3.5 Psionic Handbook as well? If not, do you know where I can find it?

Cheers!

Hello,

I noticed that you often do reviews for ENworld. I'd be willing to give you a voucher for our debut product (Remarkable Races: The Oakling, by Alluria Publishing), if you would do a review. Let me know by email, and I'll send it out right away!

Thanks!
