All my co-workers use pseudonyms…and they think I am silly for using my real name – I wonder
Do we recall when Dave just revamped the message board? It included a requirement that displayed the poster’s IP address (I found out then that one member was my co-worker and was able to tell who she is by the IP address- albeit her pseudonym…

). For us, we didn’t want to post then, because our firm is very conservative and we are cautious about our comments being misconstrued as responses provided by our employer, instead of us-as simple wannabe experts. As Chip said, paranoia runs deep.
Using a pseudonym gives you anonymity from the general public- so you may be covered in that respect. …but make sure you make no threats; reveal secrets; make incriminating comments etc… as Dave or any party who maintains the board can determine your identity through your IP address, which is always available, even if we can’t see it on the post.
