Collaboration on a template


#1

Hello,

10 months ago when I uploaded my first HTML template, a power user author sent me about converting my template to a wordpress theme and said it will take less than a month and I agreed and I opened a support ticket and sent him the collaboration ticket ID,
And since then he didn’t upload it and everytime I send him he says he will upload it soon.
So my question is, I am thinking now about working on it and uploading it myself since I have been learning wordpress for some time,
So will it be a problem if I work on it and upload it while he has a collaboration ticket from me, and does this ticket have an expiration date.

Thank you =)
