Create a new thread or update the original game thread?

Hi, can anyone inform me about how to do my next post about my upcoming iOS game without breaking the TA forum rules?



I originally posted about Man Or Goat in January 2015. I want to update the thread (or create a new thread) with a new images. Would this be regarded as bumping on TA?



As part of the thread update I also want to ask for beta testers.



Should I update the original thread with my new images and edit the title to say [BETA TESTERS WANTED].



Or should I post a new thread with my new media and ask for beta testers.



Also, would updating a thread bring it to the front page or would it stay where it is? There's no point updating a thread as far back as my original post if nobody will see it!



Should I update the original post and then reply asking for beta testers? Would that be ok?



Thanks
