I'm new here but i like the time people giving to give us back good and valuable info / soft
I believe that the option to reply just to bump up to top decrease the quality of the forum info.
This is because if there is a need to write something, like the link is missing or it's not working at all, nobody will see it
They all ignore all post below the primary one
A sticky topic will be good for popular and valuable topics and the rest should sorted down to leave the new one show themselves.
I found even spam posts created possibly from the same tools we use to spam other boards but remain for weeks or even more (i saw one from 8th of Jan.2018 for example and now is 23rd)
If there is an option with the "Thank you" function to unhide the content then it would be great and much much better from filling the forum database with thank you messages, creating more storage cpu/hdd needs without offering a cent of additional functionality for the forum
That's my opinion
