First of all, madam, I think you should start your own blog, if you haven't already. You're much more amusing than I am. Mrs. Curmudgeon thought "Pandas Revealed" far superior to any of my witticisms.
Secondly, a "personal parish" is as follows:
Can 518 (1983 Code of Canon Law): As a general rule a prish is to be territorial, that is, one which includes all the Christian faithful of a certian territory. When it is expedient, however, personal parishes are to be established determined by reason of the rite, language, or nationality of the Christian failthful of some territory, or evn for some other reason.
A parish is a juridic person with some rights (however precarious under the new regime). Many places (e.g., Denver, Rockford, Sacramento, Kansas City Missouri) have traditional communities which are established as personal parishes or their equivalents. Others (e.g., our little group) are mere "chaplaincies," with no rights, but which exist only at the sufferance of the ordinary. That's not to say there aren't risks to personal parishes (see Scranton PA), but they're not entirely a plaything of the chancery as St. Rose Philippine is.
