NO.1 Actions usually be set in "Accessories," which on ur "Inventory" Tab."Put On" First, then type in one of the triggers words above to trigger a pose, whlie in 3D chat. Though poses have no time limit, not the expressions.

NO.2 Let me talk something about using Expressions. Each expressions is as the same as trigger a pose. Each of them will last ten or more second.You can use any of the expressions included on any of the poses. So..Any time if you want to change expressions there is a only way is that you must wait till the expression returns back to default expression.OR another expression will be merging and mixed.

NO.3 Further more, If U need no expression just use a Anti Expression avatar.That will be OK.. Leave a message to me FOR MORE HELP.THX.^^.
