There are many such similar Forums on www sites on the web and 'pseudonyms' appears to be the norm for postings. However while my display posting is as RDS@MES there is never any intention to hide behind any of my comments. Many of my department's documents are signed off as RDS.
Huw - could you not ammend the 'Profile for' entries with a line for people to have their full name displayed as an item of choice. If so you may ammend mine as Richard Steventon.
I do find the site very useful and would certainly welcome an uplifting in 'Professional' presentation of entered comments and thus be more willing to spread the word to colleagues about the site.
