To the one user who sent me a message about my avatar a few days ago, which I left unanswered so far... :-( · 2:01pm Apr 22nd, 2017
I'm terribly sorry not to have answered faster.
And now, I don't even remember his (her) username anymore.
But if ever (s)he reads this, the answer is this:
My avatar is a ponification of the well-known browser Internet Explorer I found during a random internet-sailing session.
In my avatar, she says "I brought you this because it's all I'm good for."
I chose her because, well, I find her cute and I like all ponies, even Mary-Sue-ish and Gary-Stu-ish ones. :-)
