Clarification about issue on github

[Ansuel Smith]

Hi, I have a question for the issue on github.
They are only for bugs and issues on openwrt or can also be used
for asking the community for some testing? I notice some user are
present only on github and not on the forum so I wonder if a use
like that is acceptable.

(this comes from the fact that i'm pushing some clk changes upstream
and I would like to tag some user to test the changes on the SoC.
And since they are wip I don't want to create trash pr for them)
