This is just my personal opinion, before I get to that I do want to address and thank Arnox for taking in some of us refugees and being patient and resilient with the extra traffic, ddos, cp etc. Take a bow.
My opinion on the "thanks" system being integrated here is an act of a give and take. You guys were cool enough to welcome us here, but in return the forum is now much more active due to the migration. The thanks system was nice for wanting to thank someone for what they said and appreciate it. I liked that although yes our "thanked" posts were tallied up it wasn't a straight laced rep system because other people may have interests in topics that another person may not find interesting to "thank". It also brought people together in that sense as well. Lastly, I think it was a feature majority of users liked and in turn for more content on this forum now, I see it as users hoping for familiarity.
