%1<<%0 Example: Someone (ooc) Hello.%1>>%0

Seeing this or any other type of Someone "does" action..
means this character(s) is invisible. To see this person,
you must have a "See Invisible" potion, a skill or spell
that allows this type of sight.
This is also the case with "something" items.
If you still cannot see the person or item after you have
used/done one of the above items, then it is more than
likely that the person/item if of a higher level than your 
skill/spell/potion or is an invisible Immortal.
