So i've discovered a broken element in a community created sheet and I suspect i've located the source of the issue. Where do I take this information?

So I ran a Mass Effect D20 sheet last year and the one sheet that is designed for the system has a few busted macros, so in preparing for a second campaign in the system I remembered certain macros on said sheet were busted and decided to dig into the developer HTML console and see if I could locate the issue. And I believe I have located the issue with one of the busted macros but I am still digging into it further to see if there are any more issues with it that may be causing it. Essentially i just comes down to the macros not sending to chat whatsoever.  The sheet in question is simply titles, "Mass Effect" and the author is "Emre U." Now I am just curious what I am to do with this information to possibly have the sheet fixed. Anyone have any advice on where to take this information?

You could try a PM to the author , but it looks like they haven't posted anything in a long time. It also looks like like a roll20 dev has poked at it, but that may just have been to fix a compatibility issue. If Emre does not respond to a PM, I would suggest creating a specific thread in the character sheet forum with a title like "[Mass Effect] Need help fixing an issue". There are lots of folks on here with the chops to make a simple correction, and if the original author is not around, they would certainly be justified in doing so.

If you manage to figure out the fix for the macros and manage to edit & test them in a game for yourself, you can submit the fixes to the public sheet repository, or  one of the sheet author here is likely willing to submit the fix for you if done the rest.
