For chat forums where you can discuss Highland ponies with other enthusiasts. see below.
http://www.highlandponyenthusiasts.co.uk/ is the chat forum of The Highland Pony Enthusiasts club. If you want to participate, you will need to become a member of the club and pay the current subscription. I am not a member so cannot comment on the content but it seems popular.
http://talkhighlands.proboards.com/index.cgi is probably the largest chat forum with an (almost?) entirely female membership of around 300! From personal experience, I would say male members are not encouraged as there don't seem to be any! Generally ideal for teenagers who want to swap pictures of their ponies but not get involved in serious debate. Show orientated.
http://www.horseandhound.co.uk/forums/ -- while not devoted to Highland pony matters, this is the place to go for general equine discussions and advice. Obviously, a large and varied membership, some very experienced.
https://www.matchyhorsey.co.uk/showing/ -- a very comprehensive guide to showing your horse or pony.
Search Facebook for Highland pony and Highland ponies and more will come up as the scene is continually changing. These are probably the best places to go if you want to buy a Highland pony.
