This is a public forum so if users are interested then they will reply to your threads/contact you them selves. It’s fine to ask for people to participate and post details if it’s genuine, but the mods can’t make people reply to you I’m afraid.
Users here generally view the whole site, so there’s no need to make multiple threads about the same thing, a “bump” on the original thread should suffice.
A lot of the older members on here have other responsibilities in life like kids, managerial job rolls etc. so may not post as often as some of the younger guys and gals.
