Using a very large jira installations with hundreds of projects and users, it does provide a very professional look to provide emoticons icons (smileys) whenever these are found in a text string (on purpose or non-purpose). For example, posting a SQL query back as a support solution, can return "funny" looking statements, especially if subselects are used. This is just an example of when its both anoying and unprofessional looking (it becomes facebook-y).

If there was a button somewhere to enable/disable the use of smileys in the jira installation, that could be a huge benefit for us (and for many others i suppose).

We use only jira, no other atlassian product.
