I use a pseudonym as I have no desire for colleagues or clients to know of my involvement (however slight) in discussion of matters relating to ufo reports.
I generally post any input I have on issues relating to ufo reports to one of several discussion Lists and forums.
Most of the material I've posted online is about organising and searching UFO material (e.g. making available downloadable archives of searchable PDFs of the official UFO documents released by the FBI and the governments of Canada, New Zealand and Australia). I think that sort of resource may help reduce the amount of time and effort wasted within ufology reinventing the wheel.
When introducing myself in an email, I generally include two or three links to material I've posted elsewhere so people can have a glance at some of my work and see the type of issues that interest me and my approach to those issues. However, I'm not sure or not whether posting links to other forums would be frowned upon here so I'll avoid doing it unless and until a moderator says it's not rude to do that in this context.
All the best,
