The introduction of a new server certianly brings a fresh revamp on minetown, and im sure if advertised appropriately (no idea how you would do that) the revamp could bring alot of new players.
The only suggestion i would make in terms of constructive criticism, is less is more. adding improvements to a product is always good, but when theres too much change people don't like it. Keep to your roots and develop on the fundamentals which sell and you will do great. A simple, clear spawn and /marketplace, /bank (which were really well constructed, not painful on the eyes which happens with large, overly-detailed structures.) works really well. you nailed it on the classic server and i appreciated the design. I have been on servers when they just built one large spawn area with so much detail i just get a headache finding the warp signs! I just hope on main2 you have kept to such principles.
As for the item transfer from main1 to main2 - I feel you had to implement a happy medium where people could transfer some of their items from previous server, I just hope the fee for such a transfer is enough to enable a balanced fresh economic start for everyone at main2 (items or credits). I can imagine this required some thought!
Minetown certianly needed a revamp. It is also well timed, I remember Minetown being alot more popular then it is now (Im sure your income has reflected as such from donations <object class="emojione" data="

I know im being controversial saying less is more and your changing the main server, but such a risk your taking is needed to boost new players coming in. It may not appeal to the 1-2 year veterans but minetown is a business after all, and if you weren't making a single profit from this sawine I would be VERY surprised. You needed to increase player base so a new main server was a good move. I just hope the /spawn, /marketplace or /bank equivalent on main2 is designed as such so its easily navigated, and beautiful like main1.
PS - I may not know much about minecraft, i know from experience altering a product you provide too much can drastically affect outcome. Why do you think treyarch and infinity ward keep the COD series pretty much exactly the same, just different eras? Why do you think EVERY developer (Not entirely true but it bloody seems like it from what i read) are copying league of legends? Why do you think Seth makes family guy - american dad - cleaveland shows so similiar? such examples on top of my head, but you get my point. keep to a winning formula!
PPS - I havent seen main2, and i apologise if i look like an idiot and missread some of the revamps you have created. I just know by extensive research on games, trends, freinds in the gaming industry, My own business experience, what sells. all the best.
