Some examples may be in the roleplay and some simply in their description i.e. tattoos, scars or covering up imperfections, clothes etc. Hopefully these examples will generate more ideas in game for new and older players alike.Try to overcome software limitations with fantasy. When there are no technical possibilities to tie someone up it doesn't mean that you can't do it using #me commands, if all players involved take part. Only because there is no beer, doesn't mean that you can't drink in the tavern till the lights go out. If someone is drunk, he can of course stagger around, even if the server doesn't force him to.
In another online game that I played once, there was no possibility to build houses. We piled up parcels to form walls and used flour to symbolize a sand coast. The result was a town with several dozend villagers, shops and a castle that reached over many screen widths (with towers, a throne room and many luxuries). So don't let yourself be limited.
On the other hand there are logical borders, that aren't yet technicaly realized. For example you can dig in the ground with your shovel, even if the shovel is placed in your backpack instead of your hand. Also you can walk around always wearing your full armor and a whole lot of weapons without someone noticing. It is up to you, to set yourself a limit here and put away your weapons before entering a temple, take off the armor while goldsmithing and taking the shovel in the hand to dig.
