Editorial

This month marks the beginning of a new phase for Dragon User

— indeed Dragon users all over the country. As from next issue

(July 1986) Dragon User will be available to the Dragon community

BY SUBSCRIPTION ONLY. And while this means that you won't

have to trundle down to the newsagent to get your favourite read

(we'll send it to you), it does mean forking out just over a tenner

in one month, in orderto get the next 12 issues, if you don't already

have a sub. So why do it?

It's our ﬁrm belief that Dragon User is still essential reading for

all Dragon owners, beginners and experienced alike. We'll still have

all the same regular features, news and reviews, with new ones

planned even as I write! In fact, a s a controlled circulation

publication, we're hoping to pack even more in than usual —a new

upgrading series, new languages for your Dragon, teach-in's,

reader offers, competitions — we are determined to provide you

with the service and information you want for your computer.

Take the Book Offer in this month's issue w h e r e else could

you get so much for so little?

As the number of active Dragon owners has diminished (and

there's no denying that the total is down to the few tens of

thousands) it seems to us that the enthusiasm of the existing Users

has actually increased —and it's people like you we are committed

to supporting in the future.

It would be a shame if many Dragons (still a worthwhile piece

of hardware u n t i l the 0 0 0 Amiga arrives!) were put away, all for

the lack of information and a regular national magazine. No Dragon

User n o Dragon? We hope you'll join us.

I DO hope that my embarrass-

gested b y o n e o f m y v ery

satisﬁed customers, a case of

missing 'Dragons'.

He points o u t that ev ery

review normally has the Dra-

gons right or left justiﬁed —

whereas these two are cen-

tred, suggesting that two have

been dropped off the right-

hand corner.

Should the two Dragons be

his considered opinion, then I

am obviously wasting my time

RE User Groups and the Dra-

aspects of the Dragon and the

The National Dragon User's

from 'lunatic fringe" to dedi-

All that is required is enthu-
