I can’t imagine using a busy support forum without clear topic titles – either as a user or a helper.
Titles are important enough that default trust level settings let experienced (TL3+) users edit them. Don’t even have to be moderators.
I’m not the most experienced Meta-phile here but I’ll occasionally change a vague title – like “Why does this keep happening?” – to describe the actual problem, so the person has a better chance of getting help (and so any help provided can be found by others in the future.)
A little guide to titling topics, with examples, is a good idea to include in onboarding material. And if your askers are bad at titles, it might take a period of a lot of editing to set good precedents. But they’re important to both askers and helpers.
