So many memories I don't even know where to begin. I'll just list the ones that immediately come to mind:
Being a member of the Epics Critics Club was great. Had tons of fun reviewing epics and hanging out with my fellow critics on Skype (most of whom I'm still friends with, actually).
Posting (and, more importantly, finishing) my first ever comedy, My Bionicle Road Trip, was pretty fun, too. Yeah, it was terribly written dreck, but it was my terribly written dreck. The comedy itself is not on BZP anymore (you can thank the Dataclysm for that), but I will always remember the fun times I had with my readers and the fun times I had writing the crazy thing.
Being able to ask Greg questions about the Bionicle story was really awesome. How many other fandoms get to talk directly to the writer of the franchise itself? It may very well have been one of BZP's best selling points back in the old days. It was definitely one of my favorite parts.
BZP has given me a lot of good memories and experiences over the years. It hasn't been completely perfect, obviously, but I don't regret joining this site for one minute. The good times and good experiences, for me at least, trump the bad ones every time, and always will.
