Too many good memories, probably the best was picking up some good people as the time went by. Made some great friendships, built some fun/great things with said friends. Were always ups and downs but the time was well spent and enjoyable all the same.
Don't have any pictures and some details are foggy but I do recall a few things.
SMP beta, Relkeb's sea wall and draining of part of an ocean, the winding road around mountains leaving spawn with Nikita and Co. Some great early builds around the time as well.
The original SMP world out of beta (the glory days), building an insanely laggy chicken killing pen, towns and cities forming with groups of friends, single people putting in a bunch of time to make some really nice builds themselves.
Can't forget the rise of the melon farms.
Too much to name, and to remember all at once.
The community may be smaller now, people may have moved on, but community remaining is still as strong as ever.
