@jhabdas, I didn't know that Gitea and Gogs were sharing the same code base until I learnt a bit more about the projects and the schism. Once I learnt about it, I thought I should give you guys a heads-up.

@techknowlogick: thanks for that! Can you thank "@PentesterLab" or "Louis from PentesterLab (pentesterlab.com)" for example instead of snyff.

@snyff sounds good. The blog post PR is here: https://github.com/go-gitea/blog/pull/82/files#diff-e0f59ce8bb7e55f0518fc0ecafac06d7 is that suitable, or would you prefer something else.
