I'll think you will find that wherever you will go, you will always have people slagging off the team whether its the official boards or non-official ones. At the end of the day, we are all Rovers fans and have the right to have our own opinions on the club whether we choose to 'slag' them off or just praise them non-stop. If we all shared the same opinions then the messageboards would be dull places to hang around and communicate in!
In the last 4-5 years, I felt the official boards have been pretty good in terms of having a community of Rovers fans from around the country as there have been many friends made and lots of meet ups/charity events etc and sometimes it gets undeserved abuse towards it because rival clubs came on the rovers board and caused arguments, which was why the boards were shut down towards the end of last season.
Now that the new official site has a brand new messageboard, hopefully the community will once again build up and the messageboard will be more controlled by the admin + moderators due to the improvements made in terms of the features Mods now have, as before all they could really do was delete posts rather than merging, editing, create polls etc.
I feel that this messageboard is excellent in how it is run and maybe the only reasons why some topics are becoming 'boring' is because it is approaching the new season and there isnt much Rovers news about at the moment and not much is really happening due to people being on holiday or just taking a break and enjoying the good weather we've had lately (apart from the brief storm we had! ).
One thing I felt could have been improved was the welcoming of new members to the site. When I first joined I wrote a lot of posts as there were a lot of topics which I took an interest in but got told off for writing too many posts, which is understandable when people write short one line answers, but when people write good quality answers and get abuse for it, I felt it was uncalled for and quite childish.
As soon as the season starts up again and people are meeting each other before games, im sure we will all look back at this thread and think "god! we must have been bored without football!!"
