It can't have escaped notice that the 'Infrastructure Solutions' forum seems to be the "dumping ground" for loads of first posts which should be in other forums.
The reason has now been explained by Pisc86:
"I don't choose the correct forum because I click on '+ New' without seeing below the forum selected by default.
It would be very useful to give the possibility to choose the forum after clicking '+ New' button."
In the main Forums page:
pressing that '+New' button does, indeed, create a post in the 'Infrastructure Solutions' forum - without prompting, or offering any choice:
Right, as a temporary measure, I have moved the Infrastructure forum to a sub group. The forum is still accessible via the forum directory, the only change is that the New button is now gone and users will have to select their forum before asking.
All going to plan, we will be reorganising the forums soon and I'll have an update on that shortly.
