Some small improvements for content authors

I have added some small improvements to the site that may help posters.

There are two new buttons in the editor toolbar at the top of the text area when you create a post:

The Insert Quote button allows you to insert quotes with an author specified:

It is a truth universally acknowledged, that a single man in possession of a good fortune, must be in want of a wife.

Jane Austen

With the Boxout button you can create a box inserted into the text which you can use the summarize/highlight an important point:

Primitive Elvish: voiced stops unvoiced before voiceless consonants

voiced stops unvoiced before voiceless consonants; [{bdg}{ptkpʰtʰkʰs}] > [{ptk}{ptkpʰtʰkʰs}]

In Primitive Elvish, voiced stops were unvoiced where they appeared before a voiceless stop, aspirate or [s]. Tolkien described this change in both versions of the Tengwesta Quenderinwa, from the 1930s [TQ1] and the 1950s [TQ2]:

Primitive Elvish: nasals assimilated to following stops and aspirates

nasals assimilated to following stops and aspirates; [{nŋ}{ppʰb}|{mŋ}{ttʰd}|{mn}{kkʰg}] > [m{ppʰb}|n{ttʰd}|ŋ{kkʰg}]

In Primitive Elvish, nasals assimilated to following stops and aspirates. It seems this change occurred first for the velar nasal [ŋ], somewhat later for the dental nasal [n] and may have occurred for the labial nasal [m] only after the Common Eldarin period, though the assimilation of [m] does seem to occur in a very ancient period for all the Eldarin child languages (Quenya, Sindarin and Telerin).

Old Sindarin: [p], [t], [k] spirantalized before [s]

OS. [p], [t], [k] spirantalized before [s]; [ps|ts|ks] > [ɸɸ|θθ|xx]

In (Old) Sindarin and (Old) Noldorin, voiceless stops [p, t, k] became spirants before [s]. Tolkien described these changes for Old Noldorin in his notes on the use of the Feanorian Alphabet from the 1930s. The tengwar representations for the compendia characters in these quotes is approximate, since they are not supported in current tengwar fonts:
