|
* - The smiley parsing function which makes pretty faces appear :). |
|
63
|
|
|
* - If custom smiley sets are turned off by smiley_enable, the default set of smileys will be used. |
|
64
|
|
|
* - These are specifically not parsed in code tags [url=mailto:[email protected]] |
|
65
|
|
|
* - Caches the smileys from the database or array in memory. |
|
66
|
|
|
* - Doesn't return anything, but rather modifies message directly. |
