I've held back from this as I run little now and never race, but my 2 pennyworth is as follows.
I think the forum does need updating, easier to post photos would be one thing.
I am slightly against the addition of like/dislike buttons, they are great for the ego when a post is smothered with "likes" but it can also work against a forumite. If someone is a little outspoken or makes themselves unpopular they will be hit with dislikes on every post (virtual stalkers take this to extremes). This could almost be classified as forum bullying and can certainly hinder open debates on controversial matters with some not bothering to post or dropping out - preferable to being seen to be unpopular.
The buttons are a mix of good and bad, but for me the bad can slightly outweigh the good so I would not have them.

I've never done facebook or seen the fell runners one, but the situation with this forum and the FB equivallent sound exactly the same as my fishing forums - the majority head for FB with repetative questions and mindless opinions, whilst a few remain on the forums and debate or discuss more. Perhaps things will turn around in time, but a better presented forum would be more appealing to those looking in.
I have no objection to using my name but as everyone knows me as Moley I prefer to use that on here - and nobody is removing my sacred Mole avatar!! I quite understand if some wish to remain anonymous and don't have a problem with it. If we want to use our real names then add it to our visible personal profiles. Anyway, it is a bit of fun when a YT or similar turns up to cause opinionated havoc .
