As above..Trying to get on site for booking and saying page not available.. Maybe just me? 
It's just you, it's working fine for me. Perhaps try restarting your browser or using a different one.
While you're stuck here though you should have a read of the site rules (
https://www.ukpunting.com/index.php?topic=252680.0), particularly rules 1 & 27:
1 Site ethos / mission
This Forum puts the interests of Punters first through the sharing of Reviews. The Forum does not endorse or promote any service provider or any other site. This site is totally independent. No favoritism, no special treatment, no vested interests and no pandering to service providers.
Members are expected to post Reviews although there is no formal quota (see rule 27). General chat relating to Punting is allowed on the appropriate Board.
27 Lurking / Dormant Accounts
Members that do not contribute Reviews or where their accounts become dormant may have their membership revoked.You've been a member for 4 years so it's about time you start contributing.
