I don't mean to cut you off, Panupat, but I need to get back to the subject of hardcoded punctuation.
I just noticed another small issue involving different applications of hardcoded punctuation after the same types of phrase. On the Current Visitors page, the variable for the visitor's most recent activity is followed by a space:
[ATTACH=full]15301[/ATTACH]
In the user profile popup, it's followed by a comma-space:
[ATTACH=full]15302[/ATTACH]
I had been thinking I could add a Japanese colon to the end of each such phrase; that would look good on the Current Visitors page. Then I realized I was getting a Japanese colon followed by an English comma on the popup, which doesn't look good at all.
If we're going to have hardcoded punctuation after phrases, then it should be the same punctuation in every instance where the phrase is used. That would make it easier for localizers to work around the hardcoding.
But it would still be best if each of the above instances could be worked into phrases, since in Japanese the "when" part usually comes at the beginning of the sentence. For example, if the two phrases displayed in each of these two locations could be abstracted as variables named "latest_activity" and "latest_activity_time", then I could do something like this for the Current Visitors page:
{lastest_activity_time}に{latest_activity}でした。
and something like this for the popup:
{name}は、{lastest_activity_time}に{latest_activity}に目撃されました。
This is a slightly advanced version of the suggestion I made in my previous post regarding the information listed under the titles of topics in the Search Results page. I don't know how practical it is, though. Is it even possible to include a phrase name variable as part of another phrase? 
If it can be done, it would certainly be my preferred solution.
