The following is a reply to enquiries posted in the Line Dancing comments which I thought might be informative for all by posting it here in the General Forum.
Dear Sadliu and Onlysue,
Practically all CCs conduct line-dancing classes from elementary to advance level.
SHC line dancers congregate at 2 venues that I know of :
1) Sat. public dancing at Far East Square, China St. from 7 to 10.30pm
2) Wed. Practice sessions at rooftop of Blk.146A Toa Payoh (opp. HDB Hub) from 7.15pm onwards.
At the moment, SHC line dancers are working hard at these 2 venues in preparation to perform for the SHC Annual D&D on 24 Mar.
Make your way to any of these venues and you will meet the SHC line dancers.
In general:
It is easier for line dancers to pick up social dance than for social dancers to pick up line dancing. The reason : line dance steps incorporate steps from other forms of dancing such as cha cha, sambal, rumba, latin, broadway, jazz, waltz, etc. Line dance step comprises a set of 8 counts versus 4 in other forms of dancing. A simple line dance ususally have a minimum of 32 counts.
How fast one picks up line dancing depend very much on the individual. Some are ‘natural’ dancers, some work hard to achieve, some just go with the flow. Whatever the case might be, one thing for sure – line dancers will keep their body and mind healthy because it is not just physical exercise, but brain work as well.
Caution :
Some line dancers stressed themselves out by trying too hard to "master" every dance. In the end, they get ‘burned out’. One should try one’s best within one’s limit so that one can enjoy the music as well as the pleasure of dancing.

All are welcome. Hope you can come join in the fun as well.! 
Am already stressed out reading thru the finer pts of line dancing ….if i had to take a year to learn waltz elementary, and with line dancing blending rumba, chacha, think i had to say tata forever to line dancing & be content with watching the silky moves of the dancers from the by-lines. Must surely agree that it’s a good exercise for body & brain, unlike lion danz which has a lot of prancing to do.
